General Comments:


1995Ry03 (also 1995Le14): few events of 98In were identified by analyzing fragments by tof method in Ni(112Sn,X) reaction at E=58 MeV/nucleon.

2001Ki13, 2002Fa13, 2002StZZ, 2007WeZX: 98In produced and identified in 9Be(112Sn,X) at 1 GeV/nucleon followed by isotopic fragment separation

2012Lo08, 2008Ba53: 98In produced from fragmentation of a 112Sn beam at E=120 MeV/nucleon on a 195 mg/cm2 9Be target at the National Superconducting Cyclotron Laboratory (NSCL). Fragments separated by the A1900 Fragment Separator and the Radio Frequency Fragment Separator (RFFS). Ions were implanted in the double-sided silicon strip detector (DSSD). Detection system: NSCL Beta Counting System in conjunction with the SeGA Array of 16 HPGe detectors. Measured Eγ, Iγ, β spectra, E(p), I(p), βγ-coin, βp-coin, γβp-coin, half-life, β-delayed proton emission probability. Production σ=3.8 pb 12 (2008Ba53) from 216|+21 events assigned to 98In. Total of 20 and 40 βp coin events identified for the ground state and isomer, respectively. Decay curves were fitted with Poisson distribution using log-likelihood function by consideration of decay of parent, daughter and grand-daughter.

2011StZV: 98In produced in 9Be(124Xe,X), E=1 GeV/nucleon at GSI. Measured half-life from implants-β-correlated decay curve

2019Pa16: E(124Xe)=345 MeV/nucleon beam incident on a 740 mg/cm2 thick 9Be target at the RIKEN-RIBF facility. The identification of the nuclide of interest was made through the BigRIPS separator and the ZeroDegree spectrometer by determining the atomic number and the mass-to-charge ratio of the ion using the tof-Bρ-ΔE method. The secondary beam was stopped in the double-sided silicon strip detector of the WAS3ABi spectrometer. The γ rays were detected by EURICA array comprising of 84 HPGe detectors. Measured Eγ, βγ-coin, βp-coin, βpγ-coin, half-lives by βγ(t), βp(t). Deduced β+ end-point energies, Q(ε) value, excitation energy of the (9+) isomer. Comparisons with previous experimental data and shell-model calculations.

Theory references: consult the NSR database ( for 9 primary references, 8 dealing with nuclear structure calculations, and one with decay modes and half-life.

Q-value: Estimated uncertainties (2017Wa10): 500 for S(n) and Q(α), 420 for S(p).

Q-value: Q(εp)=9640 320, S(2n)=32150 580, S(2p)=3960 310 (syst,2017Wa10).
